Hey everyone i own a 2006 acura tl and well my tl was plague with the engine misfire and well thanks to everyone here i was able to locate my source. My issue is the coils pack wires. I guess they shorted and my tl is running on 3 coils. Anyone has a diy thread with how to actually replace them? I have search and having trouble locating what its actually called and I am having trouble removing that bar and opening the little black box with the clips. Thanks in advance

 

What are your misfire codes?

When I had 3 cylinders misfire it ended up being 1 coil pack going bad. Replaced the bad coil pack and car is running smooth again.

 

What bar?

For the electrical connector, if it's never been moved from the coil pack, you'll have to pull hard or use a tool to get the bottom edges of it and push it up while someone presses the plastic clip open.

 

Are you 100% sure it's the wires and not the plugs/coils? Because the coil pack wires are part of the engine wire harness, and to replace them would require a new wire harness for the whole engine .

 

It may be helpful, if you could post a pic., of the issue your trying to describe. As ACURAte_titTLe questions, It would be somewhat ODD, for the coil pack connector, and or wires, to short, especially, 3, at the same time. If the wiring/connector, is indeed, the problem, you have a serious concern, and need to determine, first, what actually caused the short.

 

i will take pictures of it tomorrow morning. And well its been a number of things that lead me here. I clean egr valve and port once it was clean it gave me the map sensor code and car did not die at idle. Now that the car run on i decide to test coils by swapping them around. The coils worked fine but the 1st 3 closest to the wipers have no power. I will be testing them with a volt meter to see if there power and current. I actually unplug all 3 coil and vehicle ran the same.

 

The "bar" in the rear sitting on top of the rear valve cover can be moved out of the way by removing two 10mm bolts, then you just use a bungee cord to hold it out of the way. It will not move far out at all because it strings into a main harness on top of the engine by the transmission. But you don't really need to do that unless you have super thick arms. I change spark plugs without touching that at all.

Are you positive there is no power to the back coil pack electrical plugs? To test this without starting the car, remove the fuel pump fuse from the driver's side cabin fuse box, alligator clip to the prones of the coil pack electrical plugs (I'm not sure what's ground and power, you'll have to find out) and look for voltage when cranking. Splat that voltmeter on the windshield facing yourself so you see the voltage when cranking.

 

This piece has plugs that connect to coils. When i called the autozone they told me there are 3 different wires that are $50 a piece that what lead me to try and open it to see if indeed there its one whole piece or 3


I still have to test both pieces to see if there is power running through it.
